how does ejaculation work

Ejaculation is how semen is released from the penis during sexual climax. It happens when the body is sexually stimulated, causing muscles to contract and push semen out of the penis. It is the discharge of a sticky liquid (semen or cum) from the penis.

There is a strong link between ejaculation and male orgasm.

However, ejaculation can also happen without an orgasm. 

How does ejaculation work? This article explores ejaculation and its mechanism in detail.

How does ejaculation process work

Ejaculation occurs when the lower spinal cord is triggered by physical and mental factors, resulting in the expulsion of seminal fluid. 

It involves being sexually stimulated and the body responding.

The body’s reflexes activate to make ejaculation happen. 

The muscles in the pelvic area contract rhythmically. This helps push semen out of the penis. 

Semen is the mixture of sperm and other fluids. 

Ejaculation allows for the release of sperm and fluids from the body.

Before, we delve deep to understand ejaculation working, let’s first know the male reproductive organ which helps in attaining an ejaculation.

Ejaculation is a two-step process that consists of emission and ejection. This ejaculation is carried with the help of male reproductive organ which includes the following:

  • Vas deferens: Tubes that store sperm and transport it from the testes to the penis
  • Seminal vesicles: They are glands that produce fluids that enter the sperm
  • Prostate: It is the gland that secretes fluids that feed and protect sperm
  • Urethra: It is a tube inside the penis through which urine and sperm exit the body
  • Bladder: It is the organ in which your urine is stored until you urinate

As sperm enters the vas deferens during ejaculation, radiation forms between the walls of the testicles. The seminal vesicles and prostate contract, forcing sperm and semen into the urethra, which is initiated by the brain cells.

How does male ejacul

ation occur

Ejaculatory processes in men are controlled by their nervous systems. This comprises sexual stimulation, activation of the ejaculatory reflex, rhythmic contraction of the pelvic muscles, and ejection of sperm through the urethra. 

Ejaculation is frequently accompanied by an orgasm, or pleasure. This process results in the release of sperm and semen, which promotes reproduction and sexual enjoyment. 

Ejaculation is categorized into two stages: emission and expulsion.

Emission phase: In the first phase, sperm travels from your testicles to your prostate, where it combines with fluid to form semen. Further, your vas deferens contract, forcing the sperm toward the base of your penis.

Expulsion phase: The muscles at the base of your penis contract every 0.8 seconds during the second phase, forcing or discharging the semen out of your penis in several spurts.

Retrograde ejaculation may result if semen enters the bladder. 

Prostatic discharge occurs when the bladder neck is closed. These secretions include acid phosphatase, citric acid, zinc, and sperm cells.

During the emission phase, the bladder neck closes to prevent sperm from entering.

During the ejection phase, sperm exits the body via the urethra. 

There isn’t a specific number of times a man should ejaculate—it varies based on individual preferences and lifestyle. 

If you’re experiencing concerns such as PE or Delayed Ejaculation, it’s advisable to seek guidance from a doctor for proper evaluation and advice.
